The Incredible Hulk wasn't a requel though, it was a full blown reboot.

only to the people who actually pay attention to the films. To the casual movie goer... it could have been a sequel.

if you ignore the opening credits to TIH, (which many casual movie goer's would), and ignore the "super soldier serum" it could have easily have been a sequel... HULK had an incident, where it tore betty and bruce apart, sent her father after him, and ended in South America... TIH started in South America, already had betty and bruce torn apart.. and her trying to live her own life, and her father after him..
